Setting the Management IP Address

This chapter includes the following sections:

Management IP Address

Each server in a Cisco UCS domain must have a one or more management IP addresses assigned to its Cisco Integrated Management Controller (CIMC) or to the service profile associated with the server. Cisco UCS Manager uses these IP addresses for external access that terminates in the CIMC. This external access can be through one of the following services:

  • KVM console

  • Serial over LAN

  • An IPMI tool

The management IP addresses used to access the CIMC on a server can be out-of-band (OOB) addresses, through which traffic traverses the fabric interconnect via the management port, or inband addresses, through which traffic traverses the fabric interconnect via the fabric uplink port. Up to six IP addresses can be configured to access the CIMC on a server, two out-of-band (OOB) and four inband.

You can configure the following management IP addresses:

  • A static OOB IPv4 address assigned directly to the server

  • An OOB IPv4 address assigned to the server from a global ext-mgmt pool

  • An inband IPv4 address derived from a service profile associated with the server

  • An inband IPv4 address drawn from a management IP pool and assigned to a service profile or service profile template

  • An static inband IPv6 address assigned directly to the server

  • An inband IPv6 address derived from a service profile associated with the server

You can assign multiple management IP addresses to each CIMC on the server and to the service profile associated with the server. If you do so, you must use different IP addresses for each of them.

A management IP address that is assigned to a service profile moves with that service profile. If KVM or SoL sessions are active when you migrate the service profile to another server, Cisco UCS Manager terminates the sessions and does not restart them after the migration is completed. You configure the IP address when you create or modify a service profile.


Note

You cannot assign a static IP address to a server or service profile if that IP address has already been assigned to a server or service profile in the Cisco UCS domain. If you attempt to do so, Cisco UCS Manager warns you that the IP address is already in use and rejects the configuration.

              Procedure
                Step 1   In the Navigation pane, click the Servers tab.
                Step 2   On the Servers tab, expand Servers > Service Profiles.
                Step 3   Expand the node for the organization that contains the service profile for which you want to set the management IP addresses.

                If the system does not include multitenancy, expand the root node.

                  Configuring the Management IP Pool

                  Management IP Pools

                  The default management IP pool ext-mgmt is a collection of external IPv4 and IPv6 addresses. Cisco UCS Manager reserves each block of IP addresses in the management IP pool for external access that terminates in the CIMC on a server.

                  You can configure separate out-of-band IPv4 address pools, and inband IPv4 or IPv6 address pools. You can configured inband pools that contain both IPv4 and IPv6 address blocks.


                  Tip

                  To avoid assigning an IP pool that contains only IPv4 addresses as the inband IPv6 policy, or assigning an IP pool that contains only IPv6 addresses as the inband IPv4 policy to a server CIMC, it is suggested that you configure separate inband address pools, each with only IPv4 or IPv6 addresses.

                  You can configure service profiles and service profile templates to use IP addresses from the management IP pools. You cannot configure servers to use the management IP pool.

                  All IP addresses in the management IP pool must be in the same IPv4 subnet, or have the same IPv6 network prefix as the IP address of the fabric interconnect.


                  Note

                  The management IP pool must not contain any IP addresses that have been assigned as static IP addresses for a server or service profile.

                  Creating an IPv4 Address Block in the Management IP Pool

                  The management IP pool must not contain any IP addresses that have been assigned as static IP addresses for a server or service profile.

                  Procedure
                    Step 1   In the Navigation pane, click the LAN tab.
                    Step 2   In the LAN tab, expand LAN > Pools > Organization_Name .
                    Step 3   Expand the IP Pools node.
                    Step 4   Right-click IP Pool ext-mgmt and select Create Block of IP Addresses.
                    Step 5   In the Create a Block of IPv4 Addresses dialog box, complete the following fields:
                    Name Description

                    Name column

                    The range of IPv4 addresses assigned to the block.

                    From column

                    The first IPv4 address in the block.

                    To column

                    The last IPv4 address in the block.

                    Subnet column

                    The subnet mask associated with the IPv4 addresses in the block.

                    Default Gateway column

                    The default gateway associated with the IPv4 addresses in the block.

                    Primary DNS column

                    The primary DNS server that this block of IPv4 addresses should access.

                    Secondary DNS column

                    The secondary DNS server that this block of IPv4 addresses should access.

                    Step 6   Click OK.
                    What to Do Next

                    Configure one or more service profiles or service profile templates to obtain the CIMC IP address from the management IP pool.

                    Creating an IPv6 Address Block in the Management IP Pool

                    The management IP pool must not contain any IP addresses that have been assigned as static IP addresses for a server or service profile.

                    Procedure
                      Step 1   In the Navigation pane, click the LAN tab.
                      Step 2   In the LAN tab, expand LAN > Pools > Organization_Name .
                      Step 3   Expand the IP Pools node.
                      Step 4   Right-click IP Pool ext-mgmt and select Create Block of IP Addresses.
                      Step 5   In the Create a Block of IPv6 Addresses dialog box, specify the required information.
                      Step 6   Click OK.
                      What to Do Next

                      Configure one or more service profiles or service profile templates to obtain the CIMC IP address from the management IP pool.

                      Deleting an IP Address Block from the Management IP Pool

                      Procedure
                        Step 1   In the Navigation pane, click the LAN tab.

                        Step 3   Expand the IP Pools node.
                        Step 4   Select IP Pool ext-mgmt.
                        Step 5   Right-click the IP address block that you want to delete and select Delete.
                        Step 6   If the Cisco UCS Manager GUI displays a confirmation dialog box, click Yes.
